Photo 2, Week 3; (May 1-5) TIME EXPOSURE Photography

Please describe: ​How does Shutter Speed Effect the Result of a Photograph?

Copy these notes 5-1,Only the underlined is required to be written:

Called Long-exposure or time-exposure, slow-shutter photography involves using a long-duration shutter speed to sharply capture the stationary elements of images while blurring, smearing, or obscuring the moving elements.

How Long do you think the Star trail photograph took to take?

​How long do you think the waterfall picture took to take?

"How To" Tips:(what we will do in-class)​A) Use a Tripod​

B) Focus before you start using Manual focus (or set to infinity)

C) Set the DSLR camera to a long shutter speed using the Mode set to TV (Time-value and then choose a slow time like from 10-30 seconds)

​D) Set the ISO to the least sensitive (100) then adjust upward if you need to brighter (more sensitive).

Marey and Demeny developed several photographic techniques to study the movements of everything from humans to horses; 127 years ago, light painting was first used for scientific study

office workers wearing small lights 102 years ago (when your great grandmother was born) What could this man have been at work doing?

Man Ray (1930's) accomplished this technique by setting up his camera to produce a self-portrait, opening the shutter and using a small penlight to make a sequence of swirls and linear images in the air.

How long do you think the shutter would have to be open to capture all this movement in Man Ray's Space Writing?

History of Light painting...

Light Painting, or Light Drawing, is a technique in which photos are made while making a long exposure and using light in a way that it builds up exposure in the picture. If you do a search for "light painting" and light drawing" on the web you will see an amazing variety of techniques and styles.​​Let's look at how light painting began in 1889: Of course this is all film photography, digital photography did not become common until the mid to late 1990s.

​Étienne-Jules Marey and Georges Demeny, 1889:Marey and Demeny developed several photographic techniques to study the movements of everything from humans to horses; 127 years ago, light painting was first used for scientific study (see the photos to the left).

Frank Gilbreth: Light Painting Photography, 1914In the year 1914 Frank Gilbreth, along with his wife Lillian Moller Gilbreth, used small lights and the open shutter of a camera to track the motion of manufacturing and clerical workers. The Gilbreth’s did not create these light painting photographs as an artistic endeavor; they instead were studying what they called “work simplification”. The Gilbreth’s were working on developing ways to increase employee output and simplify their jobs.https://archive.org/details/OriginalFilm

100 years ago, Scientists used light "writing" as a means to study movement. Later, the technique sparked artists imagination!

​Remember Man Ray??? He made Photograms, but he called them Rayograms.

What do you think he called his light paintings?

In Man Ray's 1930's series 'Space Writings,' Man Ray became one of the first ARTIST to explore the technique of 'light painting.'Man Ray mainly considered himself a painter, so the bridgebetween paint and photograph was revolutionary for his workand for all artists across time.

In the 1940’s photographer Gjon attached small lights to the boots of ice skaters he then opened the shutter of his camera long enough for the skater to complete a few turns; these photos inspired Picasso:

what you think is creating the effect in the pictures below:(Pablo Picasso tried this technique after seeing those photos above of the skater in the 1940s-1950s)

Eric Staller could be called the Father of Light Graffiti (also known as Light Drawing, Writing, or Painting, in its present day form).

From 1976 to 1980 Staller roamed the dark streets of New York City creating light painting photographs:

These were done around 1980 - before digital photography (digital was not commonplace until around 1995) - so this is using color film.

In Photo 2 Class we will use this concept with digital cameras to explore Digital Photography.

Resolution refers to how many pixels in an inch. There is high and low resolution

Resolution (or also called the dpi) : describes how many pixels in a photo, written in a number that tells how many “dots” Per square inch of the image; two examples are - 72 dpi(which is very low resolution) or 300dpi (which is a high resolution). dpi can be higher but is only necessary if you are enlarging the image to be a poster or a billboard size. For normal everyday size prints, 300 dpi is fine.

ABOVE: This is an enlargement of the edge of th "O" above. The left image shows a lower resolution than the right image; the more pixels that make up an image the more detailed and smooth edged it will be. The one on the left will look blurry when reduced, the one on the right will look cleaner and crisper to the naked eye.

For use on the web use 72 dots per inch (looks “OK” on a screen)But Best for printing – is 300 dpi, it will have more detail, see below

Sometimes Pictures come out of cameras HUUUUUUGE but at a low resolution of 72, huge photos are big files and are hard to store, work with, or save to flash drives, email, or even to use on the web. The web likes 72 dpi resolution-it travels through the internet easier. Photographers do not like 72 dpi, it is not detailed enough to PRINT from.

To work in Photoshop and print, you should change all photos from 72 dpi to 300 dpi at "image size" also changing the size of the image in that same window to about 9” by 12” or else the images will be 5 feet wide. This is an enlargement of how a photo looks if you don't do this:

SD Cards: Secure Digital (SD) is a memory card format developed for use in portable devices which has become the industry standard. (The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita Electric) and Toshiba as an improvement over MultiMediaCards (MMC).

DCIM: Digital Camera Images, a directory name in the Design rule for Camera File system (DCF, or “Design rule for Camera File system”), part of the file system for a digital camera. On a computer, when you open the folder for the SD card you may see subfolders, the one that says DCIM will hold the images.

The DCIM folders on smartphones serve the same purpose. When you connect an iPhone or Android phone to your computer, the computer or photo-library software can notice the DCIM folder, notice there are photos that can be transferred, and offer to do this automatically.

DCIM may not be the most obvious name the first time you see it — how about “Photos”? — but it’s more important that it’s a standard. If every digital camera manufacturer or smartphone operating system had its own unique pictures folder, software programs wouldn’t always be able to automatically find photos on a connected device. You wouldn’t be able to take an SD card from one camera and plug it directly into another digital camera, accessing the photos without reformatting the device or rearranging the file system.

Care must be taken inserting card!Class Activities: After demonstrations in class, you will work in groups and create digital light painting photos in class. Before a class starts to take the photos for the day, they will take a picture of the date and period so that the segment of photos is easily seen on the SD card when opened in a folder on the computer. Drag and drop the photos you worked on into your own folder. Open in Photoshop CC and edit them. Resave as a Photopaint file and a JPG file. Also save your photos to the flash drive so the teacher has access to your work. Once a number of your photos are completed we will pick the best ones for printing in class and putting on this web site in a slide show.
